iPod Touch: delete icon?

OOops! I added an extra "Home page" icon for Safari...now I have two, cluttering the screen. I have no idea how to delete one. How?

This, plus, if someone would kindly direct me to a good online user's guide or a good book for purchase that'll train me for such details, I may keep my butt off the board here, and quit cluttering this space with pickayuunee questions! (Makes me feel doltish!)
